Beyond Trauma Exposure: Discrimination and Posttraumatic Stress, Internalizing, and Externalizing Problems Among Detained Youth.

According to the race-based traumatic stress model, racial discrimination is proposed to comprise a traumatic experience that results in posttraumatic stress symptoms, as well as internalizing and externalizing problems among youth. Accordingly, a significant body of research has emerged that supports the associations among these constructs. However, the majority of these empirical studies have not accounted for the potential role of traditionally defined traumatic events in these associations. This study investigated whether self-reported racial discrimination was related to posttraumatic stress symptoms, internalizing, and externalizing symptoms above and beyond the impact of other trauma exposures in a sample of 266 detained youth (79% boys, 60% identified as an ethnic minority). Results of hierarchical linear regressions demonstrated that, after accounting for youths' other trauma exposures, racial discrimination accounted for significant variance in the models predicting delinquency and risk-taking but no other externalizing and internalizing problems, or posttraumatic stress symptoms. These findings indicate that racial discrimination may be particularly important for understanding offending behavior among detained youth.

Intimate Partner Violence in Adolescence: Associations With Perpetration Trauma, Rumination, and Posttraumatic Stress.

Engagement in intimate partner violence (IPV) is related to a host of negative outcomes for youth, including posttraumatic stress symptoms (PTSS). Moreover, research indicates that the perpetration of violence may constitute a traumatic experience, termed perpetration trauma (PT), which, in turn, is related to elevated levels of PTSS. Little research to date, however, has illuminated the underlying processes that may link IPV perpetration, PT, and PTSS. One potential contributor to this association is rumination on negative emotions. In particular, for youth who report PT and rumination, engaging in IPV may be associated with elevations in PTSS. To investigate this hypothesis, data were gathered from a sample of 235 justice-involved youth (184 boys, 51 girls) who completed self-report measures of IPV perpetration and victimization, PT, sadness and anger rumination, and PTSS. Results of moderated mediational analyses indicated that IPV perpetration was related to PTSS through sadness rumination, and that these effects were stronger when youth endorsed PT. In turn, IPV perpetration was related to PTSS through anger rumination only when youth did not endorse PT. In addition, tests of alternative models indicated that these results were specific to IPV perpetration, given that IPV victimization was not related to PTSS through anger or sadness rumination when youth endorsed PT. These results suggest that the combination of rumination on sadness and endorsement of PT may put youth who perpetrate IPV at the greatest risk of PTSS. Therefore, interventions seeking to interrupt the cycle of IPV perpetration may benefit from targeting perpetrators' sadness rumination, PT, and PTSS.

Trauma exposure, posttraumatic overmodulation and undermodulation, and nonsuicidal self-injury in traumatized justice-involved adolescents.

OBJECTIVE: Previous research has established associations among childhood trauma exposure, posttraumatic stress symptoms (PTSSs), and adolescent nonsuicidal self-injury (NSSI). In fact, numerous studies have suggested that PTSSs may serve as a mechanism linking trauma exposure and NSSI. However, studies to date have not utilized newer models of PTSSs that differentiate between symptoms of overmodulation and undermodulation. This study investigated associations among interpersonal and noninterpersonal trauma exposure, posttraumatic overmodulation and undermodulation, and NSSI in a sample of justice-involved youth. METHOD: Participants were 566 youth (2 transgender youth, 142 girls, and 422 boys). On average, youth were 16 years old (SD = 1.27), and approximately half self-identified as an ethnic minority. Participants completed measures of lifetime trauma exposure and NSSI, and past-month PTSSs. RESULTS: Structural equation modeling demonstrated that interpersonal trauma exposure was associated with symptoms of overmodulation (95% confidence interval [CI] [.180, .340]) and undermodulation (95% CI [.179, .338]) as well as NSSI (95% CI [.156, .572]). Additionally, symptoms of overmodulation were differentially associated with NSSI (95% CI [.158, .720]), and there was a significant indirect effect between interpersonal trauma exposure and NSSI via overmodulation (95% CI [.015, .095]). CONCLUSIONS: This study highlights the utility of conceptualizing posttraumatic stress disorder as a disorder of emotion regulation characterized by symptoms of overmodulation and undermodulation, and has clinical implications for mental health professionals who interact with youth in the justice system.

The roles of trauma exposure, rejection sensitivity, and callous-unemotional traits in the aggressive behavior of justice-involved youth: A moderated mediation model.

Research has demonstrated an association between childhood trauma exposure and adolescent aggression. This association may be explained by rejection sensitivity, defined as anger, or anxiety in the anticipation of rejection, which can be a consequence of trauma exposure. Callous-unemotional (CU) traits also are associated with trauma exposure and aggressive behavior; however, research has not yet investigated the interactive roles that rejection sensitivity and CU traits play in the relation between trauma exposure and aggression. Therefore, this study sought to investigate the role of rejection sensitivity in the association between trauma exposure and aggression, and whether this indirect effect was moderated by CU traits. Participants included 380 detained youth (98 girls, 282 boys) who completed self-report measures of trauma exposure, angry, and anxious rejection sensitivity, CU traits, and aggression. Results of moderated mediation demonstrated that the relation between trauma exposure and aggression exhibited an indirect effect through angry rejection sensitivity, but only at moderate or high levels of CU traits. This pattern was not found for anxious rejection sensitivity. Results suggest that interventions aimed to decrease aggressive behavior in traumatized adolescents may benefit from considering how youth respond to rejection, as well as whether youth endorse CU traits, as this may help to limit further involvement in the juvenile justice system after release.

Posttraumatic Stress, Family Functioning, and Externalizing in Adolescents Exposed to Violence: A Moderated Mediation Model.

Exposure to community violence disproportionately impacts low-income, minority youth and is associated with posttraumatic stress symptoms and maladaptive adjustment. This study investigates whether posttraumatic stress mediates the relation between exposure to community violence and externalizing symptoms and the moderating role of family cohesion and daily family support in buffering these effects on later externalizing. Low-income, African American 7th-grade students (M age = 12.57 years; N = 254) from high-crime neighborhoods participated in a 2-year longitudinal study measuring the effects of community violence exposure. The students completed questionnaires administered by research staff over 5 consecutive days for each year of the study. Family cohesion and daily family support exhibited a significant buffering effect for several outcomes. Posttraumatic stress significantly mediated the effect of witnessing community violence on subsequent aggression. The strength of these indirect effects depended on level of family cohesion. The findings provide evidence in support of interventions provided at both individual and family levels. Mental health providers working with this population should be aware of the intertwined nature of exposure to community violence, posttraumatic stress, and subsequent maladaptive outcomes.

The Role of Neighborhood in the Development of Aggression in Urban African American Youth: A Multilevel Analysis.

The purpose of this study was to examine the role of neighborhood disadvantage and perceptions of neighborhood on the development of aggressive behavior among a sample of urban low-income African American middle school aged youth (mean age = 11.65 years). Results of hierarchical linear modeling indicated that youth experienced significant changes in rates of aggression across the three middle school years, and that on average, negative youth perceptions of neighborhood predicted increases in aggression. Both parent and youth perceptions of neighborhood disadvantage trended toward significance as a moderator between objective neighborhood characteristics and aggression. These results are in accordance with past research, which suggests that personal evaluations of the disadvantage of a neighborhood influence child development and behavior. Future studies should examine the role that perceptions play in youth development, as well as in interventions geared towards thwarting youth aggression.
